Youve probably seen our ads in Welding Journal and The Fabricator making it clear that Thoriated tungsten is not going anywhere. Do not blow dust off clothing or skin with compressed air. . Thoriated Tungsten Electrodes WT20 2% Thoriated Tungsten Electrodes (AWS classification EWTh-2) contain a minimum of 97.30 per cent tungsten and 1.70 to 2.20 per cent thorium and are called 2 per cent thoriated. TWI Ltd (Head Office) Granta Park, Great Abington, Cambridge, CB21 6AL, UK +44(0 . Potential Hazards These welding rods contain a small amount of radioactive material; therefore, potential low-level external and internal radiation hazards exist. The latest innovation in tungsten electrodes, E3 offers excellent ignition characteristics and more consistent welding properties than 2% thoriated. They are large, slow moving radioactive particles that pose little risk if some very basic work practices are observed: 1) Use a grinder that captures the grinding dust from the tungsten sharpener (I know everyone has a wheel dedicated to just sharpening tungsten!) Been using 2% thor.for 30 years and still cancer free! Thoriated (Color Code: Red) - Thoriated tungsten electrodes (AWS classification EWTh-2) contain a minimum of 97.30 percent tungsten and 1.70 to 2.20 percent thorium and are called 2 percent thoriated. Thoriated oxide content of 2% (WT20) thoriated tungsten electrode has a better operating performance than other thoriated tungsten electrode. Environmental Precautions: Do not allow to enter drains or to be released to the environment. This email address is being protected from spambots. It is the most widely used tungsten due to it's long life, improved arc starting, stability, and less tungsten contamination in the weld. Seek medical attention if symptoms persist.
